Answer 1

Question No 1

Given details are

Patient weight is 12 pounds (12lbs)

Drug concentration 12mg/ml, but 1 ml = 1 cc, Hence, 12mg / 1cc

Dosage rate is 10 mg per kg

Taking into all these considerations

12lbs	X	1kg	X	10mg	X	1ml	X	1cc
1	2.2lbs	1kg	2mg	1ml

12lbs	X	1kg	X	10mg	X	1ml	X	1cc
1	2.2lbs	1kg	2mg	1ml

12 X 1 X 10 X 1 X 1	cc
1 X 2.2 X 1 X 2 X 1

120	cc

Question no 2

Question No 2

Given details are

Patient weight is 105 pounds (105lbs)

Drug concentration 100mg/ml, but 1 ml = 1 cc, Hence, 100mg / 1cc

Dosage rate is 15 mg per kg

Taking into all these considerations

105lbs	X	1kg	X	15mg	X	1ml	X	1cc
1	2.2lbs	1kg	100mg	1ml

105lbs	X	1kg	X	15mg	X	1ml	X	1cc
1	2.2lbs	1kg	100mg	1ml

105 X 1 X 15 X 1 X 1	cc
1 X 2.2 X 1 X 100 X 1
